Spirit: Not happening!

Round 1

IT'S THE BATTLE TO SAVE THE WORLD!

FIGHT!

The battle was explosive. Even though the struggle went back and forth, the heroes were easily gaining the upper hand.

Everyone: HADOKEN!

Everyone shot Hadokens, they hit Leviathan and Mammon with amazing force.

Leviathan and Mammon: Demon Flame!

The demonic fireball hit everyone head on, but did little damage.

Everyone: KAMEHAMEHA!

Massive damage.

Leviathan and Mammon: Demon Inferno!

Still little damage. By this time, the rest of the heroes had regained consciousness.

Sunset: What the?

Wolverine: The hell's going on here?

Siege: Guys, head back to base.

Tommy: What?

Reznov: You expect us to leave you here?

Mason: Are you mad? You'll die!

Spirit: We'll make it! Just go!

Nightwing: I think we should go, guys. Let's leave this to them.

Mason: Alright, fine. Godspeed guys.

Reznov: For victory, my friends! For victory!

Then, the rest of Siege Alliance and Team Spirit left.

Siege: For victory, Reznov.

Siege then focused on the battle at hand.

Leviathan: Time to die!

Leviathan and Mammon started charging up their ultimate attack, Demon Hellfire.

Siege: Not happening!

Everyone then began to charge up the Metsu Kamehameha.

Everyone: Metsu… Ka… me… ha… me…

Leviathan: Die fools!

Leviathan and Mammon: Demon Hellfire!

Siege: You're the one who will die!

Everyone: HAAAAAAAA!

The attacks collided, going back and forth. Then, Leviathan and Mammon began to get the upper hand.

Leviathan: YOUR DEATH NOW COMES!

Siege gritted his teeth.

Siege: NEVER!

The energy blast surged with energy and blasted through Demon Hellfire.

Leviathan: WHAT!?

The blast then started to encase Mammon and Leviathan.

Mammon: No, no! This can't be!

Leviathan: No! How is this possible? How are they-

Leviathan was being encased by the blast before he could finish.

Leviathan: GUAAAAAAAAAHHHH!

K.O.!

ULTRA COMBO FINISH!

Siege and Spirit walked up to the corpses of Leviathan and Mammon. Leviathan then coughed up some blood.

Leviathan (weakly chuckling): So, Spirit. You and your friends managed to defeat me. Congratulations. But, this is not over.

Spirit: Not by a long shot. This battle is mine, however.

Leviathan (weakly chuckles again): Of course, but with your life.

Leviathan then held up his finger. It was the Death Beam.

Siege remembered his promise to his brother.

Flashback

Siege's Brother: Don't let anyone else you care about die, please promise me… Promise… Me…

Siege: I promise bro… I promise…

End Flashback

Siege then pushed Spirit out of the way of the Death Beam.

Siege: NO!

Siege was then shot with the beam.

Siege: GAH!

Siege reverted back to normal.

Siege (chuckling): See you in hell, demon!

Leviathan looked at Siege's hands, they were glowing blue.

Siege: HADOKEN…

Dead on hit. Leviathan's head was then blown off. The demon lords then teleported away, including their leader's corpse.

Siege then fell to the ground, dying.

Spirit: SIEGE!

Spirit ran to his friend's side.

Siege (weakly): H-hey Spirit.

Spirit: Siege, you can't die, we are one. We can't lose you.

Siege: Spirit, that's the thing about war. Everything comes with a sacrifice.

Spirit: Why? Why did you save me from Leviathan?

Siege (weakly): Because I made a promise to my brother not to let anyone else die. Plus, you said it yourself Spirit.

Siege then uttered his last words.

Siege: We are one…

Siege then died.

Spirit: Siege! No…

Spirit was shedding some tears.

Spirit: No, no, no, no… Siege…

Spirit was now crying.

Akuma, Raiden, Goku, Ryu, and Inuyasha lowered their heads.

Twilight was crying as well.

Inuyasha then remembered that the Tensaiga could resurrect the dead.

Inuyasha: Bring him back to headquarters.

Twilight (still crying): So we can bury him, right?

Inuyasha: No. So we can revive him.

Everyone else: Huh?

Inuyasha: I'll explain on the way.


Damn, what a way for my OC to go out. But, if Inuyasha's plan works, I'll be happy.

10-4 readers! Siege out!
